ABSTRACT

The present invention relates to certain SGLT-2 inhibitors for treating and/or preventing metabolic disorders, such as type 1 or type 2 diabetes mellitus or pre-diabetes, in patients with renal impairment or chronic kidney disease (CKD).

TECHNICAL FIELD OF THE INVENTION

The present invention relates to certain SGLT-2 inhibitors for treatingand/or preventing metabolic disorders, such as type 2 or type 1 diabetesmellitus or pre-diabetes, in patients with renal impairment or chronickidney disease (CDK).

BACKGROUND OF THE INVENTION

Diabetes is a major public health problem, with a prevalence that isexpected to reach 552 million people worldwide by 2030. Type 2 diabetesmellitus (T2DM) accounts for 90% of all diabetes cases. Most medicationsfor the treatment of T2DM act through insulin-dependent mechanisms; theprogressive loss of beta-cell function that is characteristic of T2DMmeans that most patients with T2DM ultimately require multiple therapiesto maintain glycemic control.

Nephropathy is a well-established complication of poor glycemic controlin patients with diabetes. An estimated 10-36% of patients with T2DMhave some degree of renal impairment and chronic kidney disease (CKD) ispresent in approximately 40% of patients with diabetes. CKD has beenclassified into 5 stages, where stage 1 is kidney damage with normal GFR(mL/min/1.73 m²) of ≧90; stage 2 is kidney damage with a mild decreasein GFR (GFR 60-89); stage 3 is a moderate decrease in GFR (GFR 30-59);stage 4 is a severe decrease in GFR (GFR 15-29); and stage 5 is kidneyfailure (GFR <15 or dialysis). The use of a number of anti-diabetesagents is restricted in patients with renal impairment. Metformin iscontraindicated in patients with renal dysfunction due to the risk ofaccumulation and lactic acidosis. Caution is advised with the use ofinsulin secretagogues in renally impaired patients. The DPP-4 inhibitorssaxagliptin, sitagliptin and vildagliptin (but not linagliptin) arepredominantly excreted renally, so dose reduction is necessary inpatients with advanced chronic kidney disease.

There is therefore a need for methods, medicaments and pharmaceuticalcompositions for the treatment of metabolic disorders, such as type 2diabetes, in patients with renal impairment or chronic kidney disease(CDK).

DEFINITIONS

The term “active ingredient” of a pharmaceutical composition accordingto the present invention means the SGLT2 inhibitor according to thepresent invention. An “active ingredient is also sometimes referred toherein as an “active substance”.

The term “body mass index” or “BMI” of a human patient is defined as theweight in kilograms divided by the square of the height in meters, suchthat BMI has units of kg/m².

The term “overweight” is defined as the condition wherein the individualhas a BMI greater than or 25 kg/m² and less than 30 kg/m. The terms“overweight” and “pre-obese” are used interchangeably.

The terms “obesity” or “being obese” and the like are defined as thecondition wherein the 15 individual has a BMI equal to or greater than30 kg/m. According to a WHO definition the term obesity may becategorized as follows: the term “class I obesity” is the conditionwherein the BMI is equal to or greater than 30 kg/m² but lower than 35kg/m²; the term “class II obesity” is the condition wherein the BMI isequal to or greater than 35 kg/m² but lower than 40 kg/m=; the term“class III obesity” is the condition wherein the BMI is equal to orgreater 20 than 40 kg/m².

The indication obesity includes in particular exogenic obesity,hyperinsulinaemic obesity, hyperplasmic obesity, hyperphyseal adiposity,hypoplasmic obesity, hypothyroid obesity, hypothalamic obesity,symptomatic obesity, infantile obesity, upper body obesity, alimentaryobesity, hypogonadal obesity, central obesity, visceral obesity,abdominal obesity.

The term “visceral obesity” is defined as the condition wherein awaist-to-hip ratio of greater than or equal to 1.0 in men and 0.8 inwomen is measured. It defines the risk for insulin resistance and thedevelopment of pre-diabetes.

The term “abdominal obesity” is usually defined as the condition whereinthe waist circumference is >40 inches or 102 cm in men, and is >35inches or 94 cm in women. With regard to a Japanese ethnicity orJapanese patients abdominal obesity may be defined as waistcircumference ≧85 cm in men and a ≧90 cm in women (see e.g.investigating committee 35 for the diagnosis of metabolic syndrome inJapan).

The term “euglycemia” is defined as the condition in which a subject hasa fasting blood glucose concentration within the normal range, greaterthan 70 mg/dL (3.89 mmol/L) and less than 100 mg/dL (5.6 mmol/L). Theword “fasting” has the usual meaning as a medical term.

The term “hyperglycemia” is defined as the condition in which a subjecthas a fasting blood glucose concentration above the normal range,greater than 100 mg/dL (5.6 mmol/L). The word “fasting” has the usualmeaning as a medical term.

The term “hypoglycemia” is defined as the condition in which a subjecthas a blood glucose concentration below the normal range, in particularbelow 70 mg/dL (3.89 mmol/L).

The term “postprandial hyperglycemia” is defined as the condition inwhich a subject has a 2 hour postprandial blood glucose or serum glucoseconcentration greater than 200 mg/dL (11.11 mmol/L).

The term “Impaired fasting blood glucose” or “IFG” is defined as thecondition in which a subject has a fasting blood glucose concentrationor fasting serum glucose concentration in a 20 range from 100 to 125mg/dl (i.e. from 5.6 to 6.9 mmol/l), in particular greater than 110mg/dL and less than 126 mg/dl (7.00 mmol/L). A subject with “normalfasting glucose” has a fasting glucose concentration smaller than 100mg/dl, i.e. smaller than 5.6 mmol/l.

The term “Impaired glucose tolerance” or “IGT” is defined as thecondition in which a subject has a 2 hour postprandial blood glucose orserum glucose concentration greater than 140 mg/dl (7.78 mmol/L) andless than 200 mg/dL (11.11 mmol/L). The abnormal glucose tolerance, i.e.the 2 hour postprandial blood glucose or serum glucose concentration canbe measured as the blood sugar level in mg of glucose per dL of plasma 2hours after taking 75 g of glucose after a fast. A subject with “normalglucose tolerance” has a 2 hour postprandial blood glucose or serumglucose concentration smaller than 140 mg/dl (7.78 mmol/L).

The term “hyperinsulinemia” is defined as the condition in which asubject with insulin resistance, with or without euglycemia, has fastingor postprandial serum or plasma insulin concentration elevated abovethat of normal, lean individuals without insulin resistance, having awaist-to-hip ratio <1.0 (for men) or <0.8 (for women).

The terms “insulin-sensitizing”, “insulin resistance-improving” or“insulin resistance-lowering” are synonymous and used interchangeably.

The term “insulin resistance” is defined as a state in which circulatinginsulin levels in excess of the normal response to a glucose load arerequired to maintain the euglycemic state (Ford E S, et al. JAMA. (2002)287:356-9). A method of determining insulin resistance is theeuglycaemic-hyperinsulinaemic clamp test. The ratio of insulin toglucose is determined within the scope of a combined insulin-glucoseinfusion technique. There is found to be insulin resistance if theglucose absorption is below the 25th percentile of the backgroundpopulation investigated (WHO definition). Rather less laborious than theclamp test are so called minimal models in which, during an intravenousglucose tolerance test, the insulin and glucose concentrations in theblood are measured at fixed time intervals and from these the insulinresistance is calculated. With this method, it is not possible todistinguish between hepatic and peripheral insulin resistance.

Furthermore, insulin resistance, the response of a patient with insulinresistance to therapy, insulin sensitivity and hyperinsulinemia may bequantified by assessing the “homeostasis model assessment to insulinresistance (HOMA-IR)” score, a reliable indicator of insulin resistance(Katsuki A, et al. Diabetes Care 2001; 24: 362-5). Further reference ismade to methods for the determination of the HOMA-index for insulinsensitivity (Matthews et al., Diabetologia 1985, 28: 412-19), of theratio of intact proinsulin to insulin (Forst et al., Diabetes 2003,52(Suppl. 1): A459) and to an euglycemic clamp study. In addition,plasma adiponectin levels can be monitored as a potential surrogate ofinsulin sensitivity. The estimate of insulin resistance by thehomeostasis assessment model (HOMA)-IR score is calculated with theformula (Galvin P, et al. Diabet Med 1992; 9:921-8):

HOMA-IR=[fasting serum insulin (pU/mL)]×[fasting plasmaglucose(mmol/L)/22.5]

Insulin resistance can be confirmed in these individuals by calculatingthe HOMA-IR score. For the purpose of this invention, insulin resistanceis defined as the clinical condition in which an individual has aHOMA-IR score >4.0 or a HOMA-IR score above the upper limit of normal asdefined for the laboratory performing the glucose and insulin assays.

As a rule, other parameters are used in everyday clinical practice toassess insulin 35 resistance. Preferably, the patient's triglycerideconcentration is used, for example, as increased triglyceride levelscorrelate significantly with the presence of insulin resistance.

Individuals likely to have insulin resistance are those who have two ormore of the following attributes: 1) overweight or obese, 2) high bloodpressure, 3) hyperlipidemia, 4) one or more 1^(st) degree relative witha diagnosis of IGT or IFG or type 2 diabetes.

Patients with a predisposition for the development of IGT or IFG or type2 diabetes are those having euglycemia with hyperinsulinemia and are bydefinition, insulin resistant. A typical patient with insulin resistanceis usually overweight or obese. If insulin resistance can be detected,this is a particularly strong indication of the presence ofpre-diabetes. Thus, it may be that in order to maintain glucosehomoeostasis a person needs 2-3 times as much insulin as a healthyperson, without this resulting in any clinical symptoms.

“Pre-diabetes” is a general term that refers to an intermediate stagebetween normal glucose tolerance (NGT) and overt type 2 diabetesmellitus (T2DM), also referred to as 15 intermediate hyperglycaemia. Assuch, it represents 3 groups of individuals, those with impaired glucosetolerance (IGT) alone, those with impaired fasting glucose (IFG) aloneor those with both IGT and IFG. IGT and IFG usually have distinctpathophysiologic etiologies, however also a mixed condition withfeatures of both can exist in patients. Therefore in the context of thepresent invention a patient being diagnosed of having “pre-diabetes” isan 20 individual with diagnosed IGT or diagnosed IFG or diagnosed withboth IGT and IFG.

Following the definition according to the American Diabetes Association(ADA) and in the context of the present invention a patient beingdiagnosed of having “pre-diabetes” is an individual with:

a) a fasting plasma glucose (FPG) concentration <100 mg/dL [1mg/dL=0.05555 mmol/L] and a 2-hour plasma glucose (PG) concentration,measured by a 75-g oral glucose tolerance test (OGTT), ranging between≧140 mg/dL and <200 mg/dL (i.e., IGT); orb) a fasting plasma glucose (FPG) concentration between ≧100 mg/dL and<126 mg/dL and a 2-hour plasma glucose (PG) concentration, measured by a75-g oral glucose tolerance test (OGTT) of <140 mg/dL (i.e., IFG); orc) a fasting plasma glucose (FPG) concentration between ≧100 mg/dL and<126 mg/dL and a 2-hour plasma glucose (PG) concentration, measured by a75-g oral glucose tolerance test (OGTT), ranging between ≧140 mg/dL and<200 mg/dL (i.e., both IGT and IFG).

Patients with “pre-diabetes” are individuals being pre-disposed to thedevelopment of type 2 diabetes. Pre-diabetes extends the definition ofIGT to include individuals with a fasting blood glucose within the highnormal range a 100 mg/dL (J. B. Meigs, et al. Diabetes 2003;52:1475-1484). The scientific and medical basis for identifyingpre-diabetes as a serious health threat is laid out in a PositionStatement entitled “The Prevention or Delay of Type 2 Diabetes” issuedjointly by the American Diabetes Association and the National Instituteof Diabetes and Digestive and Kidney Diseases (Diabetes Care 2002;25:742-749).

The methods to investigate the function of pancreatic beta-cells aresimilar to the above methods with regard to insulin sensitivity,hyperinsulinemia or insulin resistance: An improvement of beta-cellfunction can be measured for example by determining a HOMA-index forbeta-cell function (Matthews et al., Diabetologia 1985, 28: 412-19), theratio of 10 intact proinsulin to insulin (Forst et al., Diabetes 2003,52(Suppl. 1): A459), the insulin/C-peptide secretion after an oralglucose tolerance test or a meal tolerance test, or by employing ahyperglycemic clamp study and/or minimal modeling after a frequentlysampled intravenous glucose tolerance test (Stumvoll et al., Eur J ClinInvest 2001, 31: 380-81).

The term “type 1 diabetes” is defined as the condition in which asubject has, in the presence of autoimmunity towards the pancreaticbeta-cell or insulin, a fasting blood glucose or serum glucoseconcentration greater than 125 mg/dL (6.94 mmol/L). If a glucosetolerance test is carried out, the blood sugar level of a diabetic willbe in excess of 200 mg of glucose per dL (11.1 mmol/l) of plasma 2 hoursafter 75 g of glucose have been taken on an empty stomach, in thepresence of autoimmunity towards the pancreatic beta cell or insulin. Ina glucose tolerance test 75 g of glucose are administered orally to thepatient being tested after 10-12 hours of fasting and the blood sugarlevel is recorded immediately before taking the glucose and 1 and 2hours after taking it. The presence of autoimmunity towards thepancreatic beta-cell may be observed by detection of circulating isletcell autoantibodies 25 [“type 1A diabetes mellitus”], i.e., at least oneof: GAD65 [glutamic acid decarboxylase-65], ICA [islet-cell cytoplasm],IA-2 [intracytoplasmatic domain of the tyrosine phosphatase-like proteinIA-2], ZnT8 [zinc-transporter-8] or anti-insulin; or other signs ofautoimmunity without the presence of typical circulating autoantibodies[type 1B diabetes], i.e. as detected through pancreatic biopsy orimaging). Typically a genetic predisposition is present (e.g. HLA, INSVNTR and PTPN22), but this is not always the case.

The term “type 2 diabetes mellitus” or “T2DM” is defined as thecondition in which a subject has a fasting blood glucose or serumglucose concentration greater than 125 mg/dL (6.94 mmol/L). Themeasurement of blood glucose values is a standard procedure in routinemedical analysis. If a glucose tolerance test is carried out, the bloodsugar level of a diabetic will be in excess of 200 mg of glucose per dL(11.1 mmol/l) of plasma 2 hours after 75 g of glucose have been taken onan empty stomach. In a glucose tolerance test 75 g of glucose areadministered orally to the patient being tested after 10-12 hours offasting and the blood sugar level is recorded immediately before takingthe glucose and 1 and 2 hours after taking it. In a healthy subject, theblood sugar level before taking the glucose will be between 60 and 110mg per dL of plasma, less than 200 mg per dL 1 hour after taking theglucose and less than 140 mg per dL after 2 hours. If after 2 hours thevalue is between 140 and 200 mg, this is regarded as abnormal glucosetolerance.

The term “late stage type 2 diabetes mellitus” includes patients with asecondary drug 10 failure, indication for insulin therapy andprogression to micro- and macrovascular complications e.g. diabeticnephropathy, or coronary heart disease (CHD).

The term “HbA1c” refers to the product of a non-enzymatic glycation ofthe haemoglobin B chain. Its determination is well known to one skilledin the art. In monitoring the treatment of diabetes mellitus the HbA1cvalue is of exceptional importance. As its production dependsessentially on the blood sugar level and the life of the erythrocytes,the HbA1c in the sense of a “blood sugar memory” reflects the averageblood sugar levels of the preceding 4-6 weeks. Diabetic patients whoseHbA1c value is consistently well adjusted by intensive diabetestreatment (i.e. <6.5% of the total haemoglobin in the sample), aresignificantly better protected against diabetic microangiopathy. Forexample, metformin on its own achieves an average improvement in theHbA1c value in the diabetic of the order of 1.0- 1.5%. This reduction ofthe HbA1C value is not sufficient in all diabetics to achieve thedesired target range of <6.5% and preferably <6% HbA1c.

The term “insufficient glycemic control” or “inadequate glycemiccontrol” in the scope of the present invention means a condition whereinpatients show HbA1c values above 6.5%, in particular above 7.0%, evenmore preferably above 7.5%, especially above 8%.

The “metabolic syndrome”, also called “syndrome X” (when used in thecontext of a metabolic disorder), also called the “dysmetabolicsyndrome” is a syndrome complex with the cardinal feature being insulinresistance (Laaksonen D E, et al. Am J Epidemiol 2002; 156:1070-7).According to the ATP III/NCEP guidelines (Executive Summary of the ThirdReport of the National Cholesterol Education Program (NCEP) Expert Panelon Detection, Evaluation, and Treatment of High Blood Cholesterol inAdults (Adult Treatment Panel III) JAMA: Joumal of the American MedicalAssociation (2001) 285:2486-2497), diagnosis of the metabolic syndromeis made when three or more of the following risk factors are present:

-   -   1. Abdominal obesity, defined as waist circumference >40 inches        or 102 cm in men, and >35 inches or 94 cm in women; or with        regard to a Japanese ethnicity or Japanese patients defined as        waist circumference ≧85 cm in men and a ≧90 cm in women;    -   2. Triglycerides: a ≧150 mg/dL    -   3. HDL-cholesterol <40 mg/dL in men    -   4. Blood pressure a ≧130/85 mm Hg (SBP ≧130 or DBP ≧85)    -   5. Fasting blood glucose a ≧100 mg/dL

The NCEP definitions have been validated (Laaksonen D E, et al. Am JEpidemiol. (2002) 156:1070-7). Triglycerides and HDL cholesterol in theblood can also be determined by standard methods in medical analysis andare described for example in Thomas L (Editor): “Labor und Diagnose”,TH-Books Verlagsgesellschaft mbH, Frankfurt/Main, 2000.

According to a commonly used definition, hypertension is diagnosed ifthe systolic blood pressure (SBP) exceeds a value of 140 mm Hg anddiastolic blood pressure (DBP) exceeds a value of 90 mm Hg. If a patientis suffering from manifest diabetes it is currently recommended that thesystolic blood pressure be reduced to a level below 130 mm Hg and thediastolic blood pressure be lowered to below 80 mm Hg.

The term “glomerular filtration rate (GFR)” is defined as the volume offluid filtered from the renal (kidney) glomerular capillaries into theBowman's capsule per unit time. It is 25 indicative of overall kidneyfunction. The glomerular filtration rate (GFR) can be calculated bymeasuring any chemical that has a steady level in the blood, and isfreely filtered but neither reabsorbed nor secreted by the kidneys. Therate therefore measured is the quantity of the substance in the urinethat originated from a calculable volume of blood. The GFR is typicallyrecorded in units of volume per time, e.g., milliliters per minute andthe formula below can be used:

GFR=(Urine Concentration×Urine Volume)/Plasma Concentration

The GFR can be determined by injecting inulin into the plasma. Sinceinulin is neither reabsorbed nor secreted by the kidney after glomerularfiltration, its rate of excretion is directly proportional to the rateof filtration of water and solutes across the glomerular filter. Anormal value is: GFR=90-125 mL/min/1.73 m², in particular GFR=100-125mL/min/1.73 m².

Other principles to determine GFR involve measuring 51Cr-EDTA,[1251]iothalamate or iohexol.

The “estimated glomerular filtration rate (eGFR)” is defined as derivedat screening from serum creatinine values based on e.g., the ChronicKidney Disease Epidemiology Collaboration (CKD-EPI) equation, theCockcroft-Gault formula or the Modification of Diet in Renal Disease(MDRD) formula, which are all known in the art.

The term “empagliflozin” refers to the SGLT2 inhibitor1-chloro-4-(β-D-glucopyranos-1-yl)-2-[4-((S)-tetrahydrofuran-3-yloxy)-benzyl]-benzeneof the formula

as described for example in WO 2005/092877. Methods of synthesis aredescribed in the literature, for example WO 06/120208 and WO2011/039108. According to this invention, it is to be understood thatthe definition of empagliflozin also comprises its hydrates, solvatesand polymorphic forms thereof, and prodrugs thereof. An advantageouscrystalline form of empagliflozin is described in WO 2006/117359 and WO2011/039107 which hereby are incorporated herein in their entirety. Thiscrystalline form possesses good solubility properties which enables agood bioavailability of the SGLT2 inhibitor. Furthermore, thecrystalline form is physico-chemically stable and thus provides a goodshelf-life stability of the pharmaceutical composition. Preferredpharmaceutical compositions, such as solid formulations for oraladministration, for example tablets, are described in WO 2010/092126,which hereby is incorporated herein in its entirety.

The terms “treatment” and “treating” comprise therapeutic treatment ofpatients having already developed said condition, in particular inmanifest form. Therapeutic treatment may be symptomatic treatment inorder to relieve the symptoms of the specific indication or causaltreatment in order to reverse or partially reverse the conditions of theindication or to stop or slow down progression of the disease. Thus thecompositions and methods of the present invention may be used forinstance as therapeutic treatment over a period of time as well as forchronic therapy.

The terms “prophylactically treating”, “preventivally treating” and“preventing” are used interchangeably and comprise a treatment ofpatients at risk to develop a condition mentioned hereinbefore, thusreducing said risk.

The term “tablet” comprises tablets without a coating and tablets withone or more coatings. Furthermore the “term” tablet comprises tabletshaving one, two, three or even more layers and press-coated tablets,wherein each of the beforementioned types of tablets may be without orwith one or more coatings.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to certain SGLT-2 inhibitors, inparticular empagliflozin, for treating and/or preventing a metabolicdisorder, in particular type 1 or type 2 diabetes or pre-diabetes and/ordiseases related thereto (e.g. diabetic complications), in patients withrenal impairment or chronic kidney disease (CKD). In one aspect, thepresent invention relates to certain SGLT-2 inhibitors, in particularempaglifbzin, for improving glycemic control in patient with type 1 ortype 2 diabetes or pre-diabetes and with renal impairment or chronickidney disease (CKD).

The treatment of type 2 diabetes typically begins with diet andexercise, followed by oral antidiabetic monotherapy, and althoughconventional monotherapy may initially control blood glucose in somepatients, it is however associated with a high secondary failure rate.The limitations of single-agent therapy for maintaining glycemic controlmay be overcome, at least in some patients, and for a limited period oftime by combining multiple drugs to achieve 20 reductions in bloodglucose that cannot be sustained during long-term therapy with singleagents. Available data support the conclusion that in most patients withtype 2 diabetes current monotherapy will fail and treatment withmultiple drugs will be required. But, because type 2 diabetes is aprogressive disease, even patients with good initial responses toconventional combination therapy will eventually require an increase ofthe dosage or further treatment with insulin because the blood glucoselevel is very difficult to maintain stable for a long period of time.Although existing combination therapy has the potential to enhanceglycemic control, it is not without limitations (especially with regardto long term efficacy). Further, traditional therapies may show anincreased risk for side effects, such as hypoglycemia or weight gain,which may compromise their efficacy and acceptability.

Thus, for many patients, these existing drug therapies result inprogressive deterioration in metabolic control despite treatment and donot sufficiently control metabolic status especially over long-term andthus fail to achieve and to maintain glycemic control in advanced orlate stage type 2 diabetes, including diabetes with inadequate glycemiccontrol despite conventional oral or non-oral antidiabetic medication.

Therefore, although intensive treatment of hyperglycemia can reduce theincidence of chronic damages, many patients with type 2 diabetes remaininadequately treated, partly because of limitations in long termefficacy, tolerability and dosing inconvenience of conventionalantihyperglycemic therapies.

This high incidence of therapeutic failure is a major contributor to thehigh rate of long-term hyperglycemia-associated complications or chronicdamages (including micro- and makrovascular complications such as e.g.diabetic nephrophathy, retinopathy or neuropathy, or cardiovascularcomplications such as e.g. myocardial infarction, stroke or vascularmortality or morbidity) in patients with type 2 diabetes.

Oral antidiabetic drugs conventionally used in therapy (such as e.g.first- or second-line, and/or mono- or (initial or add-on) combinationtherapy) include, without being restricted thereto, metformin,sulphonylureas, thiazolidinediones, glinides and α-glucosidaseinhibitors.

Non-oral (typically injected) antidiabetic drugs conventionally used intherapy (such as e.g. first- or second-line, and/or mono- or (initial oradd-on) combination therapy) include, without being restricted thereto,GLP-1 or GLP-1 analogues, and insulin or insulin analogues.

However, the use of these conventional antidiabetic or antihyperglycemicagents can be associated with various adverse effects. For example,metformin can be associated with lactic acidosis or gastrointestinalside effects; sulfonylureas, glinides and insulin or insulin analoguescan be associated with hypoglycemia and weight gain; thiazolidinedionescan be associated with edema, bone fracture, weight gain and heartfailure/cardiac effects; and alpha-glucosidase blockers and GLP-1 orGLP-1 analogues can be associated with gastrointestinal adverse effects(e.g. dyspepsia, flatulence or diarrhea, or nausea or vomiting) and,most seriously (but rare), pancreatitis.

Type 1 diabetes mellitus (Type 1 diabetes), also called insulindependent diabetes mellitus or 30 juvenile diabetes, is a form ofdiabetes mellitus that results from autoimmune destruction ofinsulin-producing beta cells of the pancreas. The subsequent lack ofinsulin leads to increased blood glucose concentrations and increasedurinary glucose excretion. The classical symptoms are polyuria,polydipsia, polyphagia, and weight loss. Type 1 diabetes may be fatalunless treated with insulin. Complications from type I diabetes are thesame or similar to complications from type 2 diabetes. Standard therapyof type 1 diabetes is insulin treatment. Therapies for type 1 diabetesare for example described in WO 2012/062698.

SGLT2 inhibitors (sodium-glucose co-transporter 2) represent a novelclass of agents that are being developed for the treatment orimprovement in glycemic control in patients with type 2 diabetes.Glucopyranosyl-substituted benzene derivative are described as SGLT2inhibitors, for example in WO 01/27128, WO 03/099836, WO 2005/092877, WO2006/034489, WO 2006/064033, WO 2006/117359, WO 2006/117360, WO2007/025943, WO 2007/028814, WO 2007/031548, WO 2007/093610, WO2007/128749, WO 2008/049923, WO 2008/055870, WO 2008/055940. Theglucopyranosyl-substituted benzene derivatives are proposed as inducersof urinary sugar excretion and as medicaments in the 10 treatment ofdiabetes.

Renal filtration and reuptake of glucose contributes, among othermechanisms, to the steady state plasma glucose concentration and cantherefore serve as an antidiabetic target. Reuptake of filtered glucoseacross epithelial cells of the kidney proceeds via sodium-dependentglucose cotransporters (SGLTs) located in the brush-border membranes inthe tubuli along the sodium gradient. There are at least 3 SGLT isoformsthat differ in their expression pattern as well as in theirphysico-chemical properties. SGLT2 is exclusively expressed in thekidney, whereas SGLT1 is expressed additionally in other tissues likeintestine, colon, skeletal and cardiac muscle. SGLT3 has been found tobe a glucose sensor 20 in interstitial cells of the intestine withoutany transport function. Potentially, other related, but not yetcharacterized genes, may contribute further to renal glucose reuptake.Under normoglycemia, glucose is completely reabsorbed by SGLTs in thekidney, whereas the reuptake capacity of the kidney is saturated atglucose concentrations higher than 10 mM, resulting in glucosuria(“diabetes mellitus”). This threshold concentration can be decreased bySGLT2-inhibition. It has been shown in experiments with the SGLTinhibitor phlorizin that SGLT-inhibition will partially inhibit thereuptake of glucose from the glomerular filtrate into the blood leadingto a decrease in blood glucose concentration and to glucosuria.

Empagliflozin is a novel SGLT2 inhibitor that is described for thetreatment or improvement in glycemic control in patients with type 2diabetes mellitus, for example in WO 05/092877, WO 06/117359, WO06/120208, WO 2010/092126, WO 2010/092123, WO 2011/039107, WO2011/039108.

Accordingly, in a particular embodiment, a SGLT-2 inhibitor within themeaning of this 35 invention is empagliflozin.

The present invention relates to a therapeutic (treatment or prevention)method as described herein, said method comprising administering aneffective amount of a SGLT-2 inhibitor as described herein and,optionally, one or more other active or therapeutic agents as describedherein to a patient with renal impairment.

Patients with renal disease, renal dysfunction or renal impairment mayinclude patients with chronic renal insufficiency or impairment, whichcan be stratified (if not otherwise noted) according to glomerularfiltration rate (GFR, ml/min/1.73 m²) into 5 disease stages: stage 1characterized by normal GFR ≧90 plus either persistent abuminuria (e.g.UACR ≧30 mg/g) or known structural or hereditary renal disease; stage 2characterized by mild reduction of GFR (GFR 60-89) describing mild renalimpairment; stage 3 characterized by moderate reduction of GFR (GFR30-59) describing moderate renal impairment; stage 4 characterized bysevere reduction of GFR (GFR 15-29) describing severe renal impairment;and terminal stage 5 characterized by requiring dialysis or GFR <15describing established kidney failure 15 (end-stage renal disease,ESRD).

Accordingly, chronic kidney disease and its stages (CKD 1-5) can beusually characterized or classified accordingly, such as based on thepresence of either kidney damage (albuminuria) or impaired estimatedglomerular filtration rate (GFR <60 [ml/min/1.73 m²], with or withoutkidney damage).

For the purpose of the present invention, the degree of renal impairmentin a patient is defined by the following estimated glomerular filtrationrate (eGFR):

Normal renal function: eGFR ≧90 ml/min/1.73 m²Mild renal impairment: eGFR ≧60 to <90 ml/min/1.73 m²Moderate renal impairment: eGFR ≧30 to <60 ml/min/1.73 m²Severe renal impairment: eGFR ≧15 to <30 ml/min/1.73 m²Kidney failure: eGFR <15 ml/min/1.73 m²

Accordingly, in the context of the present invention, a patient withnormal renal function has an eGFR ≧90 ml/min/1.73 m², a patient withmild renal impairment has an eGFR ≧60 to <90 ml/min/1.73 m², a patientwith moderate renal impairment has an eGFR ≧30 to <60 ml/min/1.73 m², apatient with severe renal impairment has an eGFR ≧15 to <30 ml/min/1.73m², a patient with kidney failure has an eGFR <15 ml/min/1.73 m².

According to the present invention moderate renal impairment can befurther divided into two sub-stages:

Moderate A renal impairment (CKD 3A): eGFR ≧45 to <60 ml/min/1.73 m²Moderate B renal impairment (CKD 3B): eGFR ≧30 to <45 ml/min/1.73 m²

Accordingly, in the context of the present invention, a patient withmoderate A renal impairment has an eGFR ≧45 to <60 ml/min/1.73 m² and apatient with moderate B renal impairment has an eGFR ≧30 to <45ml/min/1.73 m².

For the purpose of the present invention, the estimated glomerularfiltration rate (eGFR) is derived from the serum creatinine (SCr) valuebased on the MDRD formula below:

eGFR (mL/min/1.73m²)=175×[SCr (μmol/L)/88.4]−1.154×[age]−0.203×[0.742 ifpatient is female]×[1.212 if patient is of African origin]

For additional analyses, renal function can also be classified by theestimated creatinine clearance rate (eCCr) value, based on theCockcroft-Gault formula below:

eCCr (mL/min)=(140−age)×(weight in kg)×[0.85 if patient isfemale]/(72×SCr (mg/dL))

Renal function classification based on eCCr is similar to the eGFRclassification: normal renal function (≧90 mL/min), mild impairment (60to <90 mL/min), moderate impairment (30 to <60 mL/min), and severeimpairment (≧15 to <30 mL/min).

Generally, mild renal impairment according to the present inventioncorresponds to stage 2 chronic kidney disease, moderate renal impairmentaccording to the present invention generally corresponds to stage 3chronic kidney disease, and severe renal impairment according to thepresent invention generally corresponds to stage 4 chronic kidneydisease. Likewise, moderate A renal impairment according to the presentinvention generally corresponds to stage 3A chronic kidney disease andmoderate B renal impairment according 30 to the present inventiongenerally corresponds to stage 3B chronic kidney disease. Therefore, themethods and uses of SGLT-2 inhibitors, particularly empagliflozin, inthe context of the present invention and applied to patients havingrenal impairment as defined herein also apply to patients having thecorresponding stage of chronic kidney disease.

In some aspects, renal disease, renal dysfunction, or insufficiency orimpairment of renal function (including mild, moderate and/or severerenal impairment) may also be suggested (if not otherwise noted) byelevated serum creatinine levels (e.g. serum creatinine levels above theupper limit of normal for their age, e.g. ≧130−150 μmol/l, or a 1.5mg/dl (≧136 μmol/l) in men and a ≧1.4 mg/dl (≧124 μmol/l) in women) orabnormal creatinine clearance (e.g. glomerular filtration rate (GFR)≦30-60 mV/min).

In some further aspects, mild renal impairment may be also suggested (ifnot otherwise noted) by a creatinine clearance of 50-80 ml/min(approximately corresponding to serum creatine levels of ≦1.7 mg/dL inmen and ≦1.5 mg/dL in women); moderate renal impairment may be e.g.suggested (if not otherwise noted) by a creatinine clearance of 30-50ml/min 10 (approximately corresponding to serum creatinine levelsof >1.7 to ≦3.0 mg/dL in men and >1.5 to ≦2.5 mg/dL in women); andsevere renal impairment may be e.g. suggested (if not otherwise noted)by a creatinine clearance of <30 ml/min (approximately corresponding toserum creatinine levels of >3.0 mg/dL in men and >2.5 mg/dL in women).Patients with end-stage renal disease require dialysis (e.g.hemodialysis or peritoneal dialysis).

Abuminuria stages may be for example classified as disclosed hereinand/or by urine albumin creatinine ratio (such as usually UACR ≧30 mg/g,in some instances ≧20 μg/min albumin excretion rate), such as e.g.microabuminuria may be for example classified by UACR 30-300 mg/g (insome instances 20-200 μg/min) or, in another embodiment, by UACR 30-200mg/g, and/or macroabuminuria may be for example classified by UACR >300mg/g (in some instances >200 μg/min), or, in another embodiment, byUACR >200 mg/g. Very high UACR ≧2000 mg/g may be classified asnephrotic.

Accordingly, in one embodiment, the present invention provides a methodof treating type 2 diabetes in patient comprising administeringempagliflozin to the patient, wherein the patient has moderate renalimpairment (or CKD stage 3). In one embodiment, the patient has moderateA renal impairment (or CKD stage 3A). In one embodiment, the patient hasmoderate B renal impairment (or CKD stage 3B).

In a further embodiment, the present invention provides a method forimproving glycemic control in a patient with type 2 diabetes comprisingadministering empagliflozin to the patient, wherein the patient hasmoderate renal impairment (or CKD stage 3). In one embodiment, thepatient has moderate A renal impairment (or CKD stage 3A). In oneembodiment, the patient has moderate B renal impairment (or CKD stage3B).

In one aspect, in a method of the present invention, the renal functionof a patient is monitored during the treatment with empagliflozin, forexample by measuring the eGFR of the patient. For example, the renalfunction of a patient is monitored during the treatment withempaglifbzin if the eGFR of the patient is below 60 ml/min/1.73 m² orbelow 45 ml/min/1.73 m². In one aspect, in such a method, the treatmentwith empagliflozin is discontinued if the eGFR of the patient fallsbelow a certain value, for example below 30 ml/min/1.73 m² or below 45ml/min/1.73 m².

In one embodiment, diabetes patients within the meaning of thisinvention may include patients who have not previously been treated withan antidiabetic drug (drug-naïve patients). Thus, in an embodiment, thetherapies described herein may be used in naïve patients. In anotherembodiment, diabetes patients within the meaning of this invention mayinclude patients with advanced or late stage type 2 diabetes mellitus(including patients with failure to conventional antidiabetic therapy),such as e.g. patients with inadequate glycemic control on one, two ormore conventional oral and/or non-oral antidiabetic drugs as definedherein, such as e.g. patients with insufficient glycemic control despite(mono-)therapy with metformin, a thiazolidinedione (particularlypioglitazone), a sulphonylurea, a glinide, GLP-1 or GLP-1 analogue,insulin or insulin analogue, or an α-glucosidase inhibitor, or despitedual combination therapy with metformin/sulphonylurea,metformin/thiazolidinedione (particularly pioglitazone),sulphonylurea/α-glucosidase inhibitor, pioglitazone/sulphonylurea,metformin/insulin, pioglitazone/insulin or sulphonylurea/insulin. Thus,in an embodiment, the therapies described herein may be used in patientsexperienced with therapy, e.g. with conventional oral and/or non-oralantidiabetic mono- or dual or triple combination medication as mentionedherein.

A further embodiment of the diabetes patients which may be amenable tothe therapies of this invention may include, without being limited,those diabetes patients (especially type 2 diabetes) with advanced ageand/or with advanced diabetes disease, such as e.g. patients on insulintreatment, patients on triple antidiabetic oral therapy, patients withpre-existing cardiovascular events and/or patients with advanced diseaseduration (e.g. >/=5 to 10 years).

The present invention further relates to a pharmaceutical compositioncomprising a certain SGLT-2 inhibitor as defined herein, empagliflozin,for use in the therapies described herein.

When this invention refers to patients requiring treatment orprevention, it relates primarily to treatment and prevention in humans.In the scope of this invention adult patients are preferably humans ofthe age of 18 years or older. Also in the scope of this invention,patients are adolescent humans, i.e. humans of age 10 to 17 years,preferably of age 13 to 17 years. It is assumed that in a adolescentpopulation the administration of the pharmaceutical compositionaccording to the invention a very good HbA1c lowering and a very goodlowering of the fasting plasma glucose can be seen. In addition it isassumed that in an adolescent population, in particular in overweightand/or obese patients, a pronounced weight loss can be observed.

As described hereinbefore by the administration of the pharmaceuticalcomposition according to this invention and in particular in view of thehigh SGLT2 inhibitory activity of the SGLT2 inhibitors therein,excessive blood glucose is excreted through the urine of the patient, sothat no gain in weight or even a reduction in body weight may result.Therefore, a treatment or prophylaxis according to this invention isadvantageously suitable in those patients in need of such treatment orprophylaxis who are diagnosed of one or more of the conditions selectedfrom the group consisting of overweight and obesity, in particular classI obesity, class II obesity, class III obesity, visceral obesity andabdominal obesity. In addition a treatment or prophylaxis according tothis invention is advantageously suitable in those patients in which aweight increase is contraindicated. The pharmaceutical composition aswell as the methods according to the present invention allow a reductionof the HbA1c value to a desired target range, for example <7% andpreferably <6.5%, for a higher number of patients and for a longer timeof therapeutic treatment compared with a corresponding monotherapy or atherapy using only two of the combination partners.

The pharmaceutical composition according to this invention and inparticular the SGLT2 inhibitor therein exhibits a very good efficacywith regard to glycemic control, in particular in view of a reduction offasting plasma glucose, postprandial plasma glucose and/or glycosylatedhemoglobin (HbA1c). By administering a pharmaceutical compositionaccording 30 to this invention, a reduction of HbA1c equal to or greaterthan preferably 0.5%, even more preferably equal to or greater than 1.0%can be achieved and the reduction is particularly in the range from 1.0%to 2.0%.

Furthermore, the method and/or use according to this invention isadvantageously applicable 35 in those patients who show one, two or moreof the following conditions:

-   -   (a) a fasting blood glucose or serum glucose concentration        greater than 100 mg/dL, in particular greater than 125 mg/dL;    -   (b) a postprandial plasma glucose equal to or greater than 140        mg/dL;    -   (c) an HbA1c value equal to or greater than 6.5%, in particular        equal to or greater than 7.0%, especially equal to or greater        than 7.5%, even more particularly equal to or greater than 8.0%.

The present invention also discloses the use of the pharmaceuticalcomposition for improving glycemic control in patients having type 1 ortype 2 diabetes or showing first signs of pre-diabetes. Thus, theinvention also includes diabetes prevention. If therefore apharmaceutical composition according to this invention is used toimprove the glycemic control as soon as one of the above-mentioned signsof pre-diabetes is present, the onset of manifest type 2 diabetesmellitus can be delayed or prevented.

Furthermore, the pharmaceutical composition according to this inventionis particularly suitable in the treatment of patients with insulindependency, i.e. in patients who are treated or otherwise would betreated or need treatment with an insulin or a derivative of insulin ora substitute of insulin or a formulation comprising an insulin or aderivative or substitute thereof. These patients include patients withdiabetes type 2 and patients with diabetes type 1.

Therefore, according to a preferred embodiment of the present invention,there is provided a method for improving glycemic control and/or forreducing of fasting plasma glucose, of postprandial plasma glucoseand/or of glycosylated hemoglobin HbA1c in a patient in need 25 thereofwho is diagnosed with impaired glucose tolerance (IGT), impaired fastingblood glucose (IFG) with insulin resistance, with metabolic syndromeand/or with type 2 or type 1 diabetes mellitus characterized in that anSGLT2 inhibitor as defined hereinbefore and hereinafter is administeredto the patient.

According to another preferred embodiment of the present invention,there is provided a method for improving glycemic control in patients,in particular in adult patients, with type 2 diabetes mellitus as anadjunct to diet and exercise.

It can be found that by using a pharmaceutical composition according tothis invention, an 35 improvement of the glycemic control can beachieved even in those patients who have insufficient glycemic controlin particular despite treatment with an antidiabetic drug, for exampledespite maximal recommended or tolerated dose of oral monotherapy withmetformin. A maximal recommended dose with regard to metformin is forexample 2000 mg per day or 850 mg three times a day or any equivalentthereof.

Therefore, the method and/or use according to this invention isadvantageously applicable in those patients who show one, two or more ofthe following conditions:

-   -   (a) insufficient glycemic control with diet and exercise alone;    -   (b) insufficient glycemic control despite oral monotherapy with        metformin, in particular despite oral monotherapy at a maximal        tolerated dose of metformin;    -   (c) insufficient glycemic control despite oral monotherapy with        another antidiabetic agent, in particular despite oral        monotherapy at a maximal tolerated dose of the other        antidiabetic agent.

The lowering of the blood glucose level by the administration of anSGLT2 inhibitor according to this invention is insulin-independent.Therefore, a pharmaceutical composition according to this invention isparticularly suitable in the treatment of patients who are diagnosedhaving one or more of the following conditions

-   -   insulin resistance,    -   hyperinsulinemia,    -   pre-diabetes,    -   type 2 diabetes mellitus, particular having a late stage type 2        diabetes mellitus,    -   type 1 diabetes mellitus.

Furthermore, a pharmaceutical composition according to this invention isparticularly suitable in the treatment of patients who are diagnosedhaving one or more of the following conditions

-   -   (a) obesity (including class I, II and/or III obesity), visceral        obesity and/or abdominal obesity,    -   (b) triglyceride blood level a 150 mg/dL,    -   (c) HDL-cholesterol blood level <40 mg/dL in female patients and        <50 mg/dl in male patients,    -   (d) a systolic blood pressure a 130 mm Hg and a diastolic blood        pressure ≧85 mm Hg,    -   (e) a fasting blood glucose level a 100 mg/dL.

It is assumed that patients diagnosed with impaired glucose tolerance(IGT), impaired fasting blood glucose (IFG), with insulin resistanceand/or with metabolic syndrome suffer from an increased risk ofdeveloping a cardiovascular disease, such as for example myocardialinfarction, coronary heart disease, heart insufficiency, thromboembolicevents.

Furthermore, a pharmaceutical composition according to this invention isparticularly suitable in the treatment of patients after organtransplantation, in particular those patients who are diagnosed havingone or more of the following conditions

-   -   (a) a higher age, in particular above 50 years,    -   (b) male gender;    -   (c) overweight, obesity (including class I, II and/or III        obesity), visceral obesity and/or abdominal obesity,    -   (d) pre-transplant diabetes,    -   (e) immunosuppression therapy.

Furthermore, a pharmaceutical composition according to this invention isparticularly suitable in the treatment of patients who are diagnosedhaving one or more of the following conditions:

-   -   (a) hyponatremia, in particular chronicle hyponatremia;    -   (b) water intoxication;    -   (c) water retention;    -   (d) plasma sodium concentration below 135 mmol/L.

EXAMPLES Example 1 Empagliflozin in Patients with Type 2 DiabetesMellitus (T2DM) and Renal Impairment (RI)

A Phase III trial investigated the efficacy and safety of empagliflozin(EMPA) as add-on to existing therapy for 52 weeks in patients with T2DMand RI. Patients with mild RI (eGFR [MDRD equation]≧60 to <90mL/min/1.73 m²; n=290; mean age 62.6 years; mean BMI 31.5 kg/m²)received EMPA 10 or 25 mg qd or placebo (PBO). Patients with moderate RI(eGFR ≧30 to <60 mL/min/1.73 m²; n=374; mean age 64.9 years; mean BMI30.2 kg/m²) received EMPA 25 mg qd or PBO. The primary endpoint waschange from baseline in HbA_(1c) at week 24. Exploratory endpointsincluded changes from baseline in fasting plasma glucose (FPG), weightand blood pressure (BP) at week 24 (FIG. 1).

EMPA significantly reduced HbA_(1c) vs PBO at week 24. Further analysesshowed significant reductions in FPG, weight and BP. At week 24, adverseevents (AEs) were reported by 79.6%, 75.4% and 72.7% of all patients(including an exploratory group with severe RI [n=74] on EMPA 25 mg orPBO) on EMPA 10 mg, 25 mg and PBO, respectively. Hypoglycemia (plasmaglucose ≦70 mg/dL and/or requiring assistance) was reported in 23.5% ofpatients on EMPA 10 mg, 22.1% on EMPA 25 mg and 22.9% on PBO. AEsconsistent with urinary tract infection were reported in 10.2% ofpatients on EMPA 10 mg, 9.0% on EMPA 25 mg and 8.2% on PBO. AEsconsistent with genital infection were reported in 6.1% of patients onEMPA 10 mg, 2.5% on EMPA 25 mg and 1.3% on PBO.

To conclude, in patients with T2DM and mild or moderate RI, EMPA reducedHbA_(1c) weight, and BP vs PBO, and was well tolerated.

The primary endpoint was also analysed for patients with moderate A andmoderate B renal impairment. For the patients with moderate A renalimpairment, the difference to placebo for the adjusted mean change inHbA_(1c) from baseline at Week 24 was −0.46% (95% CI: −0.66, −0.27). Forthe patients with moderate B renal impairment, the difference to placebofor the adjusted mean change in HbA_(1c) from baseline at Week 24 was−0.39% (95% CI: −0.58, −0.19).

Example 2 Mixed Effects Modeling to Quantify the Effect of EmpagliflozinExposure on the Renal Glucose Threshold in Patients with Type 2 DiabetesMellitus

Empagliflozin, a selective and potent SGLT2 inhibitor, reduces renalglucose reabsorption by lowering the renal threshold for glucose(RT_(G)) leading to increased urinary glucose excretion (UGE) anddecreased plasma glucose (PG) in patients with type 2 diabetes mellitus(T2DM). This analysis aimed to quantify the impact of empagliflozin onRT_(G) by characterizing the relationship between empagliflozin exposureand UGE in patients with T2DM using nonlinear mixed-effects modeling.

A pharmacokinetic (PK)-pharmacodynamic (PD) model was developed usingUGE, PG, PK and estimated glomerular filtration rate (eGFR) data fromthree Phase I/II trials (N=223; placebo, empagliflozin 1 to 100 mg oncedaily [QD]). The model assumed that when PG>RT_(G), UGE increased withincreasing PG and eGFR; and when PG≦RT_(G) slight glucose leakage intourine occurred (estimated as fraction reabsorbed [FRAC]). Reabsorptionwas estimated by a nonlinear function parameterized in terms of maximumreabsorbed glucose concentration (G_(max)) and PG concentration to reachhalf maximum transport (K_(m)). Maximum inhibitory effect (I_(max)) andhalf maximal inhibitory concentration (IC₅₀) described inhibition ofrenal glucose absorption. RT_(G) was calculated as the differencebetween maximum reabsorption (including drug effect) and K_(M). Themodel was evaluated via bootstrap and external predictive check of anempagliflozin renal impairment study.

The parameter estimates (95% CI) were G_(max): 374 (347, 391) mg/dL;K_(m): 144 (113, 163) mg/dL; I_(max): 0.559 (0.545, 0.607); IC₅₀: 5.28(3.53, 8.91) nmol/L; FRAC: 0.999 (0.998, 0.999). The calculated RT_(G)for placebo was 230 mg/dL. RT_(G) decreased with increasingempagliflozin concentration; doses of 1, 5, 10, and 25 mg yielded RT_(G)values of 100.5, 43.8, 33.1, and 26.0 mg/dL, respectively. Externalpredictive check demonstrated unbiased prediction of UGE across a rangeof eGFR values (end-stage renal disease to normal renal function).Simulation indicated that for 10 and 25 mg QD, >50% and 90% of subjects,respectively, maintained steady-state empagliflozin concentrations >IC₈₀for RT_(G) lowering over the dosing interval.

Example 3 Pharmacokinetics and Pharmacodynamics of Empagliflozin inSubjects with Renal Impairment

Subjects.

Male and female subjects aged 18 to 75 years weighing at least 45 kg(females only) and with a body mass index (BMI) of 18 to 34 kg/m² wereeligible for inclusion in this study. Participants with normal renalfunction (eGFR >90 mL/min/1.73 m²; control) were required to have T2DM.Patients with mild renal impairment (eGFR 60-89 mL/min/1.73 m²),moderate renal impairment (eGFR 30-59 mL/min/1.73 m²), severe renalimpairment (eGFR <30 mL/min/1.73 m²) or renal failure/ESRD (requiringdialysis) did not need to have T2DM. eGFR was calculated using theModification of Diet in Renal Disease (MDRD) formula: 186×serumcreatinine^(1.154)×age^(0.203)×[0.742 if female].

Subjects were excluded from the study if they had recently participatedin a study (multiple-dose: within 2 months; single-dose: within 1month), were abusing alcohol (males >60 g/day; females >40 g/day) ordrugs, had donated >100 mL blood in the previous 4 weeks, were takingconcomitant medications known to inhibit or induce p-glycoprotein orcytochrome P450 3A, or had any medical or laboratory results deviatingfrom normal and of clinical relevance.

Subjects with renal impairment were excluded if they had significantdiseases other than renal impairment or T2DM, including moderate andsevere concurrent hepatic impairment, hemoglobin <8 g/dL indicatingsevere renal anemia (erythropoietin could be used to maintain hemoglobinlevels), and intake of drugs with a long half-life (>24 h) within theprevious month (or within 10 half-lives of that drug, if longer), exceptfor those being taken for the treatment of renal disease.

The investigators, in cooperation with nephrology centers, aimed torecruit 8 subjects for every group. Subjects with normal renal functionwere matched to those in the renal impairment groups by age (±5 years)and weight (±15%), where possible.

Study Design.

This 2-center, open-label, parallel-group study was undertaken to assessthe effect of renal function on the pharmacokinetics, pharmacodynamics,and safety of a single 50 mg dose of empagliflozin. Subjects werescreened for eligibility up to 21 days prior to study drugadministration. Following an overnight fast, subjects were admitted tothe research unit and received a 50 mg dose of empagliflozin with 240 mLof water (day 1). Water was allowed ad libitum except for 1 h before and1 h after study drug administration. Following medical surveillance for24 h, subjects were discharged (day 2) and were monitored as outpatientsuntil they attended an end-of-study examination (within 14 days afterthe last trial procedure).

Pharmacokinetic Endpoints.

One objective of the study was to determine the effect of renalimpairment on the relative bioavailability of empagliflozin, based onthe primary endpoints of AUC_(0-∞) and C_(max). Secondarypharmacokinetic endpoints included: t_(max), t_(1/2), fe₀₋₉₆,CL_(R,0-96), and plasma protein binding of empagliflozin.

Pharmacodynamic Endpoint.

The pharmacodynamic endpoint of the study was the cumulative amount ofUGE over a 24 h period following drug administration (UGE₀₋₂₄), relativeto baseline, with a baseline measurement obtained over 24 h precedingadministration of study drug.

Sample Collection and Analysis.

Approximately 124 mL of blood was taken from every subject over thecourse of the study for clinical laboratory tests (44 mL),pharmacokinetic assessments (50 mL), and determination of proteinbinding (30 mL). Blood samples for clinical laboratory testing werecollected after subjects had fasted for at least 10 h.

For quantification of empaglifbzin plasma concentrations 2.7 mL of bloodwas taken from a forearm vein in a K₃-EDTA (tripotassiumethylenediaminetetraacetic acid)-anticoagulant blood drawing tube atpre-dose and 0.33, 0.67, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 14, 24, 36,48, 72, and 96 h post-dose. Within 30 min of collection, the sampleswere centrifuged for 10 min at 2000-4000 g and 4-8° C. The EDTA plasmaobtained was stored at −18° C. until it was shipped on dry ice foranalysis.

Urine was collected over 24 h prior to drug administration and at thefollowing intervals following drug administration: 0-4, 4-8, 8-12,12-24, 24-36, 36-48, 48-72, and 72-96 h.

Urine containers were weighed empty and at the end of every samplingperiod and the difference was recorded as the urine volume (weight wasset equal to volume, i.e. 1 kg −1 L). Urine containers were refrigerateduntil 25 h after drug administration and aliquots were stored at −18° C.until shipped on dry ice for analysis.

Empagliflozin concentrations in plasma and urine were determined byvalidated high performance liquid chromatography, tandem massspectrometry (HPLC-MS/MS) assays.

Empagliflozin and the internal standard [¹³C₆]-empagliflozin wereextracted from urine or plasma by supported liquid extraction. Afterevaporation under nitrogen, the residue was reconstituted and analyzedusing liquid chromatography with MS/MS detection. The lower limit ofquantification for empagliflozin in human plasma was 1.11 nmol/L, withlinearity to 1110 nmol/L using a sample volume of 0.15 mL, and in humanurine was 4.44 nmol/L, with linearity to 4440 nmol/L using a samplevolume of 0.05 mL. For both plasma and urine, results were calculatedusing peak area ratios and calibration curves were created usingweighted (1/x²) quadratic regression.

For determination of protein binding of empagliflozin, 10 mL blood wascollected at pre-dose, 1.5 and 3 h post-dose. Blood was centrifuged for10 min at 4000 g and 4° C., and the plasma was stored at −20° C. untilit was shipped on dry ice for analysis. The binding of empagliflozin andthe internal standard [¹³C₆]-empagliflobzin to human plasma protein wasdetermined by equilibrium dialysis at 37° C. As a quality controlmeasure, protein binding analyses were performed using the pre-doseplasma samples.

Pharmacokinetic parameters were calculated using WinNonlin™ software(v5.01, Pharsight Corporation, Mountain View, Calif., USA). C_(max) andt_(max) values were directly determined from the plasma concentrationtime profiles of each subject. The apparent terminal rate constant(λ_(z)) was estimated from a regression of In(C) versus time over theterminal log-linear drug disposition portion of the concentration-timeprofiles. The t_(1/2) was calculated as the quotient of In(2) and λ_(z).Area under the plasma concentration-time curve to the last time point(AUC_(0-tz)) was calculated using the linear trapezoidal method forascending concentrations and the log trapezoidal method for descendingconcentrations. The AUC_(0-∞) value was estimated as the sum of AUC tothe last measured concentration, with the extrapolated area given by thequotient of the last measured concentration and λ_(z). The amount ofdrug (A_(e)) excreted unchanged in urine in each collection interval wasdetermined by the product of the urine concentration and the urinevolume. The fraction of the dose (f_(e)) that was excreted unchanged inurine was determined by the quotient of the sum of drug excreted overall dosing intervals and the dose administered. Renal clearance (CL_(R))was determined as the quotient of A_(e) over AUC. Cumulative UGE wascalculated using the glucose concentration measured in every urinesample collected from −24-0 h and 0-96 h after dosing. UGE (mg) wascalculated as follows: glucose concentration [mg/dL]×urine volume [dL]).Results are shown in FIGS. 2 to 6.

Statistical analysis. All subjects who provided at least one observationfor at least one primary endpoint without any protocol violationsrelevant to pharmacokinetic evaluation were included in the analysis ofrelative bioavailability (pharmacokinetic analysis set). All subjectswith a baseline UGE value (0-24 h pre-dose) and a UGE value from 0-24 hpost-dose without any protocol violations relevant to UGE analysis wereincluded in the UGE analysis set. All safety analyses were performed onall subjects who received study drug (treated set). One objective of thestudy was to investigate the relative bioavailability of empagliflozinin subjects with normal renal function (R) compared with subjects withvarious degrees of renal impairment (T1-4), by presenting pointestimators (adjusted geometric mean [gMean]T/R ratios) of AUC_(0-∞) andC_(max) and their 2-sided 90% CIs. AUC_(0-∞) and C_(max) were analyzedusing an analysis of variance (ANOVA) model on the logarithmic scaleincluding a fixed effect corresponding to the renal function (normal,mild impairment, moderate impairment, severe impairment, or renalfailure/ESRD). The change in UGE 0-24 h from baseline after drugadministration was analyzed by an analysis of covariance (ANCOVA) modelincluding baseline UGE values as a continuous covariate, and a fixedeffect corresponding to the renal function. Descriptive statistics werecalculated for all pharmacokinetic and pharmacodynamic parameters.Safety analyses were descriptive in nature.

Example 4 Empagliflozin in Patients with Type 2 Diabetes Mellitus (T2DM)and Stage 3a, 3B and 4 Chronic Kidney Disease (CKD)

A Phase III trial investigated the efficacy and safety of empagliflozin(EMPA) as add-on to existing therapy for 52 weeks in patients with T2DMand CKD stage 3A, 3B and 4. Patients with CKD stage 3A (eGFR [MDRDequation]≧45 to <60 mV/min/1.73 m²; n=180; mean [SD] age 64.5 [8.0]years; mean [SD] BMI 30.5 [5.2] kg/m²), CKD stage 3B (eGFR ≧30 to <45ml/min/1.73 m²; n=194; mean [SD] age 65.2 [9.0] years; mean [SD] BMI30.0 [5.4]kg/m²) or CKD stage 4 (eGFR ≧15 to <30 ml/min/1.73 m²; n=74;mean [SD] age 64.1 [11.1] years; mean [SD] BMI 30.4 [5.6] kg/m²)received EMPA 25 mg qd or PBO for 52 weeks. In exploratory analyses, weassessed the long-term efficacy and safety of EMPA, including changesfrom baseline in HbA_(1c) fasting plasma glucose (FPG), weight andsystolic and diastolic blood pressure (SBP and DBP) at week 52 (FIG. 7).

EMPA 25 mg significantly reduced HbA_(1c) vs PBO at week 52 in patientswith CKD stage 3A and 3B (Table). EMPA 25 mg did not reduce HbA_(1c) inpatients with CKD stage 4 (Table). EMPA significantly reduced FPG,weight, SBP and DBP in patients with CKD stage 3A, and significantlyreduced FPG and weight in patients with CKD stage 3B (Table). Reductionsin FPG, weight and BP were observed in patients with CKD stage 4(Table). During 52 weeks' treatment, adverse events (AEs) were reportedby 86.8% and 79.8% of patients with CKD stage 3A on EMPA 25 mg and PBO,respectively, by 80.2% and 86.7% of patients with CKD stage 3B on EMPA25 mg and PBO, respectively, and by 91.9% and 83.8% of patients with CKDstage 4 on EMPA 25 mg and PBO, respectively. AEs consistent with volumedepletion were reported by 4.4% and 2.2% of patients with CKD stage 3Aon EMPA 25 mg and PBO, respectively, by 3.1% of patients with CKD stage3B on EMPA 25 mg or PBO, and by 5.4% patients with CKD stage 4 on EMPA25 mg or PBO. AEs consistent with urinary tract infection were reportedby 16.5% and 18.0% of patients with CKD stage 3A on EMPA 25 mg and PBO,respectively, by 16.7% and 13.3% of patients with CKD stage 3B on EMPA25 mg and PBO, respectively, and by 18.9% and 8.1% of patients with CKDstage 4 on EMPA 25 mg and PBO, respectively.

EMPA 25 mg for 52 weeks was associated with significant and clinicallymeaningful reductions in HbA_(1c) compared with placebo in patients withT2DM and CKD stage 3A or 3B. EMPA led to favourable reductions in bodyweight and BP in patients with T2DM and CKD stage 3A, 3B or 4.

Example 5 Treatment of Type 2 Diabetes Mellitus

Treating patients with type 2 diabetes mellitus with empagliflozin, inaddition to producing an acute improvement in the glucose metabolicsituation, prevents a deterioration in the metabolic situation in thelong term. This can be observed is patients are treated for a longerperiod, e.g. 3 months to 1 year or even 1 to 6 years, with a combinationaccording to the invention and are compared with patients who have beentreated with other antidiabetic and/or antiobesity medicaments. There isevidence of therapeutic success compared with other treatments if no oronly a slight increase in the fasting glucose and/or HbA1c value isobserved. Further evidence of therapeutic success is obtained if asignificantly smaller percentage of the patients treated with acombination according to the invention, compared with patients who havereceived another treatment, undergo a deterioration in the glucosemetabolic position (e.g. an increase in the HbA1c value to >6.5% or >7%)to the point where treatment with an (additional) oral antidiabeticmedicament or with insulin or with an insulin analogue is indicated.

Example 6 Treatment of Insulin Resistance

In clinical studies running for different lengths of time (e.g. 2 weeksto 12 months) the success of the treatment is checked using ahyperinsulinaemic euglycaemic glucose clamp study. A significant rise inthe glucose infusion rate at the end of the study, compared with theinitial value or compared with a placebo group, or a group given adifferent therapy, proves the efficacy of a treatment according to theinvention in the treatment of insulin resistance.

Example 7 Treatment of Hyperglycaemia

In clinical studies running for different lengths of time (e.g. 1 day to24 months) the success of the treatment in patients with hyperglycaemiais checked by determining the fasting glucose or non-fasting glucose(e.g. after a meal or a loading test with oGTT or a defined meal). Asignificant fall in these glucose values during or at the end of thestudy, compared with the initial value or compared with a placebo group,or a group given a different therapy, proves the efficacy of acombination treatment according to the invention in the treatment ofhyperglycaemia.
